[RFC PATCH 0/2] add qinq test suite

[Dean Marx]

Hi all,

This patch series introduces a new functional test suite for
verifying QinQ (802.1ad) behavior across Poll Mode Drivers in DPDK.
While existing VLAN test coverage in DTS
includes basic single VLAN and dual VLAN tagging scenarios, 
it does not specifically validate QinQ encapsulation,
which is a distinct Ethernet frame format involving an
outer S-VLAN (Service VLAN) and an inner C-VLAN (Customer VLAN) tag.
This test suite focuses on validating both the software classification
and hardware offload capabilities provided by PMDs
for QinQ-tagged frames. The suite includes tests for:

QinQ Rx Parse - Ensures that double-tagged frames are correctly 
  classified with appropriate offload flags.
QinQ Strip - Verifies QinQ hardware stripping functionality,
  including correct VLAN Tag Control Information (TCI) handling.
QinQ Filter - Tests packet filtering logic based on S-VLAN ID.
QinQ Forwarding - Confirms both VLAN tags are preserved across 
  forwarding paths.
Mismatched TPID Handling - Tests behavior when the outer VLAN uses
  a non-standard TPID, ensuring proper fallback behavior.
